Check out the new set of Monsters Versus Aliens posters, stills and a featurette. And watch the evil genius Dr. Cockroach (Hugh Laurie) shock Reese Witherspoon's CG face (just like House!).

I'm having a hard time deciding which comical monster is more adorable — Hugh Laurie as Dr. Cockroach, PhD, or Will Arnett as The Missing Link. Either way they've really assembled the cream of the crop as far as clever comedic talent goes. I can't wait to see the big monster showdown. Also revealed in this little featurette, our monster pals are being held in monster prison, so they have to defeat the evil alien (Rainn Wilson) to win their freedom.
